I'm sure you are 100% correct on that. I used to be a community manager for a software company for six years. During that time, I had numerous conversations and meetings with product managers, developers, QA, etc. on what was wrong with the products, what customers really wanted, their frustrations, etc. In most cases, what eventually happened was already determined based on existing roadmaps and to steer the product in the direction higher-ups wanted it to go. The community manager has very little power. In most cases, they are just a buffer between the community and the real decision makers who don't want to face the community.
